Tamron patented the design of a new 200-800mm f/6.7 Full Frame lens for Sony E-mount

What you see above is the optical design of a new Tamron 200-800mm f/6.7 lens that was recently patented. Now, being a patent there is no guarantee yet this will make it into final mass production. But I absolutely think they should do this lens!

The only comparable lens is the Canon 200-800mm f/6.3-9.0 lens which is a hotseller.

Compared to the Canon, the Tamron would have a much more interesting constant aperture of f/6.3. The disadvantage of the Tamron is that the patent description states that the total length of the lens would be 41,5cm. The Canon is almost exactly 10cm shorter (31,4cm). But that’s a compromise that I can certainly live with and you?

In the same patent, Tamron also describes a shorter alternative: the 200-600mm f/5.6. In this case, the lens length is 35.4cm. This is 4cm longer than the Sony 200-600mm lens, which in turn ‘only’ has an aperture range of f/5.6-6.3. Also nice!
